Closure of the Bering Strait caused Mid-Pleistocene Transition cooling (2018)
Journal Article

The Mid-Pleistocene Transition (MPT) is characterised by cooling and lengthening glacial cycles from 600–1200 ka, thought to be driven by reductions in glacial CO2 in particular from ~900 ka onwards. Reduced high latitude upwelling, a process that re... Read More about Closure of the Bering Strait caused Mid-Pleistocene Transition cooling.

Diatom evidence of 20th century ecosystem change in Lake Baikal, Siberia (2018)
Journal Article

Lake Baikal has been experiencing limnological changes from recent atmospheric warming since the 1950s, with rising lake water temperatures, reduced ice cover duration and reduced lake surface-water mixing due to stronger thermal stratification. This... Read More about Diatom evidence of 20th century ecosystem change in Lake Baikal, Siberia.

Recent ecological change in ancient lakes (2018)
Journal Article

Ancient lakes are among the best archivists of past environmental change, having experienced more than one full glacial cycle, a wide range of climatic conditions, tectonic events, and long association with human settlements. These lakes not only rec... Read More about Recent ecological change in ancient lakes.

Modelling silicon supply during the Last Interglacial (MIS 5e) at Lake Baikal (2018)
Journal Article

Limnological reconstructions of primary productivity have demonstrated its response over Quaternary timescales to drivers such as climate change, landscape evolution and lake ontogeny. In particular, sediments from Lake Baikal, Siberia, provide a val... Read More about Modelling silicon supply during the Last Interglacial (MIS 5e) at Lake Baikal.

Lake Baikal isotope records of Holocene Central Asian precipitation (2018)
Journal Article

Climate models currently provide conflicting predictions of future climate change across Central Asia. With concern over the potential for a change in water availability to impact communities and ecosystems across the region, an understanding of hist...

Late Pliocene Marine pCO2 Reconstructions From the Subarctic Pacific Ocean (2018)
Journal Article

The development of large ice-sheets across the Northern Hemisphere during the late Pliocene and the emergence of the glacial-interglacial cycles that punctuate the Quaternary mark a significant threshold in Earth's climate history. Although a number... Read More about Late Pliocene Marine pCO2 Reconstructions From the Subarctic Pacific Ocean.

Spatial differences in dissolved silicon utilisation in Lake Baikal, Siberia: examining the impact of high diatom biomass events and eutrophication (2018)
Journal Article

Recent research has highlighted how Lake Baikal, Siberia, has responded to the direct and indirect effects of climate change (e.g., ice-cover duration), nutrient loading, and pollution, manifesting as changes in phytoplankton/zooplankton populations,...

A review of the stable isotope bio-geochemistry of the global silicon cycle and its associated trace elements (2018)
Journal Article

Silicon (Si) is the second most abundant element in the Earth’s crust and is an important nutrient in the ocean. The global Si cycle plays a critical role in regulating primary productivity and carbon cycling on the continents and in the oceans. Deve...

"Live” (stained) benthic foraminiferal living depths, stable isotopes, and taxonomy offshore South Georgia, Southern Ocean: implications for calcification depths (2018)
Journal Article

It is widely held that benthic foraminifera exhibit species-specific calcification depth preferences, with their tests recording sediment pore water chemistry at that depth (i.e. stable isotope and trace metal compositions). This assumed depth habita...

Constraining modern day silicon cycling in Lake Baikal (2017)
Journal Article

Constraining the continental silicon cycle is a key requirement in attempts to understand both nutrient fluxes to the ocean and linkages between silicon and carbon cycling over different timescales. Silicon isotope data of dissolved silica (?30SiDSi)... Read More about Constraining modern day silicon cycling in Lake Baikal.
